If you have one of these winterizing setups like most of us have you can use this to test your pump... Fill the bottle with fresh water and switch it in place with the valve.
Now turn on the pump and see if it pumps the water into your system when you turn on a sink spigot etc. If it shuts down normal when you close the sink spigot here then this will tell you the problem is some air getting into the lines between your pump and the fresh water tank...
If it still comes on and just hums then you have a spigot somewhere between the pump and the lines inside the trailer not totally turning off...
